"Study of Behavior of Magnatia,Doclination of the Donbass Heridiann.
Nauch tr. Ho3k. gorn. in-ta, Not 12j PP 16-37., 1954.
The magnetic orientation of Donbass mines was studied in connection
with the variations of the meridional. declination. Because the Makerevskays,
Declination Observatory was destroyed during the war, a possibility was
established of using the Odessa and Hishne-Devitakava Observatory using
magnctic measurements carried out at Donbass. A survey showed that variatiohe
of declina'Linns at the mines are the same at 1,000 m dept, and on the surface.

ABSTRACT: Investigations conducted by tile Leningrad Mining Institute in tile applica-
tion of echo-sounding in geological mining problem are discussed. Successful
application has been achieved in 1) echo-location surveying and in working placer
depo,'sits by dredging, 2) determining the form and size of inaccessible mining faces,
and 3) checking the state of underground brine-filled chambers. The research was
under the direction of Professor D. A. Kazakovskiy. The article contains echograms
showing the bottom deposits of Lake Gladyshevskoye, as well as a diagram depicting th(
the borehole technique used to probe unde-ground salt- and brine-filled cavities.

TITLE, Elimination of nitroenamel destruction in the zone of
welded seams
PERIODICAL: Avtomobillnaya promyshlennost', no. 4. 1960, 35
TEXT: Formation of deposit and destruction of the lacquer paint film
in the zone of welded seams was observed on automobiles AC?3 (YaAZ).
The investigation, carried out in the Central Laboratory of the Yaroslav-
skiy motornyy zavod (Yaroslavl' motor plant), disclosed that this de-
posit consists of carbonates of alkali metals. Caustic alkalis destroy
the paint film on welded seams and, by absorbing the carbon dioxide from
the atmosphere, turn into carbonates which deposit in the form of a
white coating. To investigate this process, metal plates were prepared
on which seams were welded, using for it the electrodes OMM-5 and MU-3
(MTs-7). The plates were treated by water vapor and carbon dioxide until
a white coating appeared on the welded seams. Having established the

Elimination of nitroonamolo6o D249/001
chemical composition of the coating the investigators applied a number
of weak acids solutions (phosphorus, oxalic, chromic) to remove it. The
beat results were obtained when a weak solution of chromic anhydride was
used. When the scale was removed the welded seams were tilice washed by
a solution containing 0.1% of chromic anhydride, 0.05% pciassium bi-
chromate and 0,85% water,,CAbstractor's note: Rest of the solution not
given.7 . The temperature of the solution was 60-700C.

Title IComposition and mechanism of formation of a film on iron
Periodical tZimr. fiz. khir- ?8/7,, 1327 1330, July 1954
Abstract jThe composition and mchanion of formation of an oxide film, forred
on an iron surface during alkaline burnishing., were investigated
electrochemically. Chemical-analytical and thermographic studies of
the composition of such an outside film on a burnished iron surface
led to the conclussion that this film consists Of F83q, Plus & small
amount of adsorbed moisture. It was established that the entire
process of alkali burnishing of iron and steel surfaces is a purely
electrochemical process, Four references: 3 USSR and I Germn (1920 -

X. -FeOOH transforms into 6 -Fe203 at a further temperatu-
re rise. This process discontinues at about 2900. The
process of transition from '6 -Fe203 Into D(-Fe2o3 ends
at about 6760.

ABSTRACTs In carrying out investigations with marked atoms, B.-partioles,
1-rays or combinations of both types of radiation are in
most cases used. In the introduction the author emphasizes
that 2 characteristic features of radioactive substances
must b+aken into consideration when using Its the half-life
and the energy of radioactive radiation. The use of radio-
active isotopes emitting particles of a very low energy,
as for example the hydrogen-isotope (tritium)p requires
much more sensitive methods of radiation recording. After
further statements on the advantages of the method of radio-
active isotopes section 2 of the paper deals with the ex-
change mechanism between marked ions in the solution and the

nickel samples in the absence of oxygen (where it was
proved that nickel attains a much lower activity than
cobalt),, After further concrete statements the investigation

TITLE: The Densimetric Method for Determining the Thickness of Protective
Films-on Metals
PERIODICAL: Zhurnal prikladnoy khimil, 1960, Vol. 33, No. 11, pp. 2606-2'V,
TEM The following methods are described in literature for determining the
thickness of protective films on metals:- The gravimetric method (Refs. 1-3). the
electrochemical method (Refs. 4-6), the optioal method (Refs. 7-9), the spectral
method (Ref. 10), the roentgenographic method (Ref. 11), the volumetric weight
method (Ref. 12), the determination by means of a double Lipnik's microscope
(Refs. 13-6) for transparent films, the determination by means of the spark-over
voltage, and the determination by means of the visible volume (Ref, 19). The
following method is proposed here: a sample of sheet mate5ial covered with a
protective film weighing A g and with a total area of S cm is used- This sample
is placed into a pycnometer filled with a liquid of density dl g/cnr3 and Is weigh-
ed. The obtained weight will be C g. The weight of the pycnometer with the
liqlild will be B g. The average density of the sample with protective fil:.i is

ABSTRACT: Computations.are presinted to prove the feasibility and economy
of replacing the six IVS-50072 type sealed mercury-arc rectifiers with

fier substations that supply 825 volts d-c for subway traction. The com-
.puted six-phase rectifier unit has six parallel branches per phase, with
six series-connect9d cells per branch. The number of parallel branches
is computed on the basis of peak load and surge currento taking the cir-
cuit-breaker interrupting time into consideration. The number of series-
.connected calls is.computed on the basis of the PIVIst with allowances

TEXT: The aim of this work was to investigate the intensity
and the spectral distribution of the vertical magnetic component
of the electromagnetic field ansociated with atmospheric noise in
the frequency range 2-25 cps. The measurements were carri a d Ott
in the Crimea. The atmospheric noise was received by a 5 x 10 M2
horizontal frame antenna. The block diagram of the arrangement
is given in Fig.l. The amplifier bad a symmetric input and an
asymmetric output. The maximum amplification coefficient was
2.5 x 105 and could be reduced by factors of 2.5 and 10
respectively. The amplified signals were recorded on maZnettc
tape and could also be inspected visually on the screen of an
oscillograph. The minimum detectable signal was 2 x 10-10 oe.
It was found that the rms fluctuation in the magnetic component

during October was 5 x 10-9 oe. The signals were also analysed
with an optical Fourier analyser with a resolution of 0.1 cps
(V.A. Zverev, Ye.F. Orlov, Ref.8j Pribory i tekhnika eksperimenta,
in prefls),
Fig.4 shows a typical spectrogram of atmospheric noise. The
spectrum is not flat; its intensity increases at lower wave-
lengths and there is a sharp line at 9 cps (roughly in the middle
of the picture). This line is ascribed to a cavity resonance,
in accordance with the suggestion put forward by W.O. Schumann
and H. K8nig (Ref.91 Naturwiss., v.41, 183 (1954)). it In pointed
out that the line was not observed after sunset. Fig.5 shows the
spectral density of atmospheric noise averaged over 25 sets of
observations for September and October as a function of frequency.
The slight minimum between 5 and 10 cps is interpreted as the
boundary between the atmospheric noise spectrum and the
geomagnetic micropulsation spectrum. Acknowledgments are

PURPOSE: This booklet is intended for the general public and students interested
in the geography and economics of Eastern Siberia.
COVERAGE: The material presented in this booklet is an expanded version of tin text
of a public lecture sponsored by the Irkutsk section of the Obshchestvo po
resprostraneniyu politiabeakikh i naucbnykh wanjy (Society for the prop-
agation of Political and Scientific Naawledge) and by the Vostochao-Sibirskiy fil-
ial (East Siberian Branch) of the USSR Acadevq of Sciences. The author discusses
briefly the history and geography of .3!rkutskaya oblast I x its weather conditicno
and natural resources, its population, industry, agriculture and transportation.
He foresees a bright future for Irkutskaya oblast' insofar as its industrial
potential is concerned. Its plan d industrial development is based primarily on
the existing and future 3upply of hydroelectric energy. The Bratsk hydroelectric

plant alone, which is being constructed on the Angara River, will have a 3,200,000 kv
hr. capacity. Its anni 1 cutput, estimated at 22,000,000,000 kv. hr., will equal
the combined output of the ftybysbev and Stalingrad 94%lroelectric stations and will
provide energy for the operction of a number of p1 d industrial plants. Irkutsk-
skaya oblast' is rich in golk', coal, muscovite, salt, gypsum, furs and timber. Its
timber amounts to 12 percent of the total timber available in the USSR. An oil
pipeline is plann d from Omsk and Govosibirsk to an Irkutsk refinez7 now under con-
struction. A number of existing and plann d industrial -plants and bydroelectric
power stations are mentioned. The machine-bailding industry c*nters are Irkutsk,
Usollye, Angarsk and Cheremkhovo. The author also rentions the fact that there
is no cement factory in Irkutskayn oblast' and that its network of milroads and
paved roads is one of the poorest in the USSR. A chemical industry based on the
available minerals and sawmill wastes will become me of the most important local
industries. No personalities are mentioned. 7here are no references.
